Hi @mariuszkarowski, first, Happy New Year! I'll take a look, but it doesn't seem complicated (combining fs and a memory array to manage the multiple RSS). Using @monetizer as the posting authority is the best choice (far better than using users' keys). This week, I need to finish an update for Nexus, so I'll take the time to think about it this weekend. Do you have a GitLab account? If not, how about GitHub? Don't hesitate to contact me by DM on Discord if needed.
